Put together the info

Earlier than you provoke a batch inference job for name middle transcript summarization, it’s essential to correctly format and add your knowledge. The enter knowledge must be in JSONL format, with every line representing a single transcript for summarization.

Every line in your JSONL file ought to comply with this construction:

{"recordId": "11 character alphanumeric string", "modelInput": {JSON physique}}

Right here, recordId is an 11-character alphanumeric string, working as a singular identifier for every entry. In the event you omit this area, the batch inference job will routinely add it within the output.

The format of the modelInput JSON object ought to match the physique area for the mannequin that you simply use within the InvokeModel request. For instance, when you’re utilizing Anthropic Claude 3 on Amazon Bedrock, it is best to use the MessageAPI and your mannequin enter would possibly appear like the next code:

{
"recordId": "CALL0000001", 
 "modelInput": {
     "anthropic_version": "bedrock-2023-05-31", 
     "max_tokens": 1024,
     "messages": [ { 
           "role": "user", 
           "content": [{"type":"text", "text":"Summarize the following call transcript: ...." ]} ],
      }
}

When getting ready your knowledge, be mindful the quotas for batch inference listed within the following desk.

Be certain your enter knowledge adheres to those dimension limits and format necessities for optimum processing. In case your dataset exceeds these limits, contemplating splitting it into a number of batch jobs.

Begin the batch inference job

After you’ve got ready your batch inference knowledge and saved it in Amazon S3, there are two main strategies to provoke a batch inference job: utilizing the Amazon Bedrock console or API.

1. Create an Amazon Bedrock shopper:

   import boto3
   bedrock = boto3.shopper(service_name="bedrock")

2. Configure the enter and output knowledge:

   input_data_config = {
       "s3InputDataConfig": {
           "s3Uri": "s3://{bucket_name}/{input_prefix}/your_input_data.jsonl"
       }
   }
   output_data_config = {
       "s3OutputDataConfig": {
           "s3Uri": "s3://{bucket_name}/{output_prefix}/"
       }
   }

3. Begin the batch inference job:

   response = bedrock.create_model_invocation_job(
       roleArn="arn:aws:iam::{account_id}:position/{role_name}",
       modelId="model-of-your-choice",
       jobName="your-job-name",
       inputDataConfig=input_data_config,
       outputDataConfig=output_data_config
   )

4. Retrieve and monitor the job standing:

   job_arn = response.get('jobArn')
   standing = bedrock.get_model_invocation_job(jobIdentifier=job_arn)['status']
   print(f"Job standing: {standing}")

Exchange the placeholders {bucket_name}, {input_prefix}, {output_prefix}, {account_id}, {role_name}, your-job-name, and model-of-your-choice together with your precise values.

Through the use of the AWS SDK, you’ll be able to programmatically provoke and handle batch inference jobs, enabling seamless integration together with your current workflows and automation pipelines.

Accumulate and analyze the output

When your batch inference job is full, Amazon Bedrock creates a devoted folder within the specified S3 bucket, utilizing the job ID because the folder identify. This folder comprises a abstract of the batch inference job, together with the processed inference knowledge in JSONL format.

You possibly can entry the processed output by two handy strategies: on the Amazon S3 console or programmatically utilizing the AWS SDK.

Entry the output on the Amazon S3 console

To make use of the Amazon S3 console, full the next steps:

1. On the Amazon S3 console, select Buckets within the navigation pane.
2. Navigate to the bucket you specified because the output vacation spot to your batch inference job.
3. Throughout the bucket, find the folder with the batch inference job ID.

Inside this folder, you’ll discover the processed knowledge information, which you’ll be able to browse or obtain as wanted.

Entry the output knowledge utilizing the AWS SDK

Alternatively, you’ll be able to entry the processed knowledge programmatically utilizing the AWS SDK. Within the following code instance, we present the output for the Anthropic Claude 3 mannequin. In the event you used a special mannequin, replace the parameter values in response to the mannequin you used.

The output information include not solely the processed textual content, but additionally observability knowledge and the parameters used for inference. The next is an instance in Python:

import boto3
import json

# Create an S3 shopper
s3 = boto3.shopper('s3')

# Set the S3 bucket identify and prefix for the output information
bucket_name="your-bucket-name"
prefix = 'your-output-prefix'
filename="your-output-file.jsonl.out"

# Learn the JSON file from S3
object_key = f"{prefix}{filename}"
response = s3.get_object(Bucket=bucket_name, Key=object_key)
json_data = response['Body'].learn().decode('utf-8')

# Initialize an inventory
output_data = []

# Course of the JSON knowledge. Displaying instance for Anthropic Claude 3 Mannequin (replace json keys as vital for a special fashions) 
for line in json_data.splitlines():
    knowledge = json.masses(line)
    request_id = knowledge['recordId']
    
    # Entry the processed textual content
    output_text = knowledge['modelOutput']['content'][0]['text']
    
    # Entry observability knowledge
    input_tokens = knowledge['modelOutput']['usage']['input_tokens']
    output_tokens = knowledge['modelOutput']['usage']['output_tokens']
    mannequin = knowledge['modelOutput']['model']
    stop_reason = knowledge['modelOutput']['stop_reason']
    
    # Entry inference parameters
    max_tokens = knowledge['modelInput']['max_tokens']
    temperature = knowledge['modelInput']['temperature']
    top_p = knowledge['modelInput']['top_p']
    top_k = knowledge['modelInput']['top_k']
    
    # Create a dictionary for the present document
    output_entry = {
        request_id: {
            'output_text': output_text,
            'observability': {
                'input_tokens': input_tokens,
                'output_tokens': output_tokens,
                'mannequin': mannequin,
                'stop_reason': stop_reason
            },
            'inference_params': {
                'max_tokens': max_tokens,
                'temperature': temperature,
                'top_p': top_p,
                'top_k': top_k
            }
        }
    }
    
    # Append the dictionary to the checklist
    output_data.append(output_entry)

On this instance utilizing the Anthropic Claude 3 mannequin, after we learn the output file from Amazon S3, we course of every line of the JSON knowledge. We will entry the processed textual content utilizing knowledge['modelOutput']['content'][0]['text'], the observability knowledge corresponding to enter/output tokens, mannequin, and cease purpose, and the inference parameters like max tokens, temperature, top-p, and top-k.

Within the output location specified to your batch inference job, you’ll discover a manifest.json.out file that gives a abstract of the processed data. This file contains data corresponding to the entire variety of data processed, the variety of efficiently processed data, the variety of data with errors, and the entire enter and output token counts.

You possibly can then course of this knowledge as wanted, corresponding to integrating it into your current workflows, or performing additional evaluation.

Bear in mind to exchange your-bucket-name, your-output-prefix, and your-output-file.jsonl.out together with your precise values.

Through the use of the AWS SDK, you’ll be able to programmatically entry and work with the processed knowledge, observability data, inference parameters, and the abstract data out of your batch inference jobs, enabling seamless integration together with your current workflows and knowledge pipelines.
